above the other script references and then remove any .js files that are repeated... These three particularly:<script src="webassist/forms/wa_servervalidation.js" type="text/javascript"></script><script src="webassist/forms/wa_clientvalidation.js" type="text/javascript"></script><script src="webassist/forms/WA_ShowCVV.js" type="text/javascript"></script>

Then remove the final jquery reference on the bottom of the page:<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

Once you make those changes if you still have issues post back and I'll look at the page again.
